Description

Technical Field

[0001] The utility model belongs to the technical field of ton bag processing, in particular to a tension testing machine for weaving ton bag slings. Background Art

[0002] In the bag making process, the shrinkage of recycled woven fabric is greater than that of new woven fabric. A certain margin should be left when cutting. The more recycled materials are mixed in the woven bag, the worse its anti-aging ability is. When storing, it should be placed in a cool, dark and sunlight-proof place. When using, pay attention to the time limit and do not leave it for too long. When the ton bag is working, the goods are provided by the sling for lifting. The sling needs to bear the weight of all the goods in the ton bag and needs to bear a large tensile force. Therefore, when it is put into use, it is necessary to use a tensile testing machine to test the tensile strength that the sling can withstand. However, it still has the following disadvantages in actual use:

[0003] The tensile testing machine for woven ton bag slings directly clamps the slings. When the slings are pulled, the clamping position is subjected to greater tension, and this position is directly broken, resulting in insufficient test accuracy;

[0004] The tension testing machine for woven ton bag slings directly uses electric drive when pulling the slings. During the electric drive process, the operation speed is relatively fast, which will cause uneven pulling. In addition, it is inconvenient to determine the tension of the ton bag sling through the cooperation of complex sensors during operation. Utility Model Content
